Summary

Rice plant normally grown in tropical and temperate climatic zones is often threatened by cold stress and is especially sensitive to chilling stress at the seedling and reproductive stages. Low temperature at the seedling stage can result in poor germination, stunted seedlings, yellowing or withering, and reduced tillering. Unpredictable cold snaps at the reproductive stage delay heading and result in pollen sterility, which was thought to be one of the key factors responsible for the reduction in grain yield of rice. Cold stress prevents the expression of full genetic potential of plants owing to its direct inhibition of metabolic reactions and, indirectly, through cold-induced osmotic, oxidative, and other stresses. In this chapter, various aspects of improving rice cold tolerance are discussed.
